OXNARD, Calif. -- Part 2 of the Dallas Cowboys' Twitter mailbag is ready.

In it we discuss:

Away we go:

@toddarcher: If you're expecting a ground-and-pound offense, then I would say, no, the run is not going to return to the Cowboys. But I think they will run the ball more and more effectively. The key will be their fourth-quarter running. Scott Linehan must be willing to kill the clock with the run and trust it. Jason Garrett didn't always trust the run, and there have been times that trust was not earned. I believe you'll see DeMarco Murray go from a career-high 217 carries in 2013 to 250-plus in 2014 provided he stays healthy. He's not been able to play a full season yet, so there is concern there as well. But with an offensive line with three first-round picks and a defense that will need protecting, the wise thing to do will be to run more ... once they get the lead with the passing game. They can't win games 14-10.

@toddarcher: He has a limited body of work so it is difficult for anybody to know much about his skills. He didn't have a sack in 16 games as a rookie when the Cowboys used him as a 3-4 defensive end. In his first practice last season he suffered a torn Achilles. The Cowboys believe he has the talent to be an effective pass rusher. Elite pass rusher? Not sure. He's big. He's strong. He will beat people with his strength more than his moves. Coming back from the type of injury he is coming back from, I think having five sacks would be a decent number. If he can do that, then there will be something to build upon for 2015.

@toddarcher: After two days of camp, I'll go with George Selvie, Nick Hayden, Henry Melton and Jeremy Mincey since that's how the Cowboys opened camp. But if I had to predict the line for the opener against the San Francisco 49ers I will go with Selvie, Terrell McClain, Melton and DeMarcus Lawrence. I think they end up keeping 10 defensive linemen on the 53-man roster, and whoever starts really won't matter because the snaps will be spread around. For his resume, Melton is a guy who has yet to play 60 percent of the snaps for a season. He played for Rod Marinelli with the Chicago Bears, and I think Marinelli wants to get to a rotation of eight or nine guys in a game to keep people fresh to wear down the opposing offensive line.

@toddarcher: He will play more and I don't mean that solely because he did not play much as a rookie. I think you'll see the Cowboys use the two-tight end package a lot and they will do so differently than how they operated in the past. They will not ask Gavin Escobar to put his hand on the ground every play (or even every other play). They'll use his strengths, which is the ability to go get the ball. He's more of a receiving tight end than an all-around tight end. Garrett has said he is stronger, but it's still not an overhaul. He does not have the build to be an on-the-line tight end every snap, in my opinion. He has the build of a basketball player. But that doesn't mean he can't have a significant role on the offense. I think you'll see him a lot this season.
